Abstract
Provided is a color conversion system and method. The color conversion system which converts the color of a filmed image includes: an image separation unit configured to receive a reference image including a color reference table and an action image, and separate the reference and action images from each other; a color data extraction unit configured to output color values of the color reference table included in the reference image; a control unit configured to detect change values obtained by comparing color values included in the reference image with those included in the color reference table, and generate a look-up table for converting the colors of the color reference table included in the reference image into desired colors; and an image conversion unit configured to perform color correction by converting the color values of the action image into coordinates in pixels, using the look-up table outputted from the control unit.
